Well this of course shows how things might work in one country but not in another, for example in some countries if you fight and lose you can be ordered to pay the opposing counsel. That would nix that strategy if the Fins have such a system in place.
Yep, "loser pays" is the rule in Europe including Finland.
There are some exceptions (court can decide that each side pays their own way, or decide the winner can only reclaim a reasonable amount considering the position of the loser) but the frivolous speeding ticket challenge would not be one of them.
